WINDOW FOR LOCOMOTIVE-CABS.

SPECIFICATION forming part of Letters Patent No. 586,896, dated July 20,1897.

Application filed May 20,1895. $eria1 No. 549,890. (No model.)

To ctZZ whmn it may concern:

Be it known that I, WILLIAM P. F. CARROLL, a citizen of theUnited Statesof America, residing at Portland, in the county of Cumberland and Stateof Maine, have invented certain new and useful Improvements in WVindowsfor Locomotive-Cabs; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to' make and use thesame.

My invention relates to improvements in windows for locomotive-cabs, andspecially to windows designed to project from the side of the cab and tobe capable of being folded up, both walls and top and bottom, when notin use.

It consists in the combination, with the side of a locomotive-cab, oflaterally-folding window-sash having glass therein and a top and bottomfor the same capable of being turned vertically on suitable hinges.

It further consists in the use of springhinges for the sash, means forregulating the angle of elevation of the top, and means for securing thesash and top and bottom in position.

It further consists in certain details of construction which will behereinafter fully described and claimed.

In the drawings herewith accompanying and forming a part of thisapplication, Figure my improved. window attached thereto. Fig. 2 is anend View of the same. Fig. 3 is a horizontal sectional View of Fig. l online 00 50.

line y y, the sash being omitted. Fig. 5 is a detail plan of thespring-hinge, and Fig. 6 is a sectional detail showing hood in position.

Same letters refer to like parts.

In said drawings, 0t represents'a side of a locomotive-cab, and b and 0windows therein. Attached to the side of the cab on either side of thewindow 0 are folding sashes d e and f g, d and f being attached-to thesides of the cab and e and g hingedto d and f, respectively,substantially as shown in Fig. 3, the dotted lines showingthese partswhen not has glass set therein, through which the engineer can seeforward or backward or laterally, as desired.

The hinges which connect the sash with the side of the cab and with eachother are springhinges which may have the form shown in Fig. 5, in whichit represents ears attached to the side of the cab or sash, as the casemay be; i, an ear attached to the corresponding or adjacent part of thecab or the sash, respectively, j, a journal set in said ears, and k acoil-spring arranged on said journal in such manner that it tendsautomatically to bring the two parts together. The car i has a lug Zthereon, under which the end m of said coilspring rests.

It will be seen that the part i can be readily removed from the otherpart, so that the swinging parts of the window can be quickly taken offor put on.

The top or hood n is hinged above the sash to the cab in such manner asto be adapted to turn vertically, and its angular elevation may beregulated in any convenient manneras, for example, by means of a link 0,pivotally attached to said hood and to a slide 19, arranged on the trackq, attached to the side of the cab or window and held in any requiredposition on said track by means of a setscrew 4.

It will be seen that as the window is raised or lowered the link forcessaid slide upwardly or downwardly, as the case may be.

It will be evident that when the sash are turned back in the positionshown in Fig. 3 the hood may be lowered to any required elevation toserve as an awning to keep the sun from the eyes of the engineer.

I also hinge the bottom or sill s to the cab, or the sill maybe composedof two parts, one, 25, being removably secured to the side of the cab,as seen in Fig. 4, and the other hinged thereto by a hinge u. v Thebottom of the sash has lugs o, projecting downwardly, and the sill hasspring-plates w, attached thereto and adapted to engage the lugs on thebottom of the sash, as seen in Fig. 1, when the sash and bottom are inposition.

To protect the glass from becoming covered with sleet in the case ofsnow-storms, I place over the window a hood 00, having substantially theform of an awning, but not extending downwardly quite to the bottom ofthe glass, so that a narrow horizontal opening is left, through whichthe engineer can see, the hood extending out suiiiciently far to serveas a protection to the lower part of the glass, as seen in Fig. 1, theinclined portion of the hood being shown in dotted lines and the openspace being marked 3 The operation of my improved cab-window is asfollows: hen the window is to be placed in position, the bottom or sillis raised horizontally to the position shown in Fig. 4E and the topraised above horizontal. The sash are then drawn outwardly and togetherinto the position shown in dotted lines in Fig. 3, where they are heldin position by means of the lugs in the sash engaging the socket in theplates attached to the bottom, as shown in Fig. 1. The top is then drawndown upon the sash, the whole having the positions shown in Fig. l.\Vhen notin use, the springplates are detached from the lugs and thesprings force the sash back into the position shown in Fig. 3. The sillis turned downwardly and may be held by engagement with the spring-plate(0, attached to the cab below.

It will be evident that the sash may be folded back and the bottomturned down and then the top be arranged at any convenient angle toprotect the engineer from the rays of the sun, adding to the comfort ofthe engineer and the safety of the train in consequence thereof. hen thesash, bottom, and top are in the position shown in Fig. 1, they form acomplete shield for the face and eye of the engineer and at the sametime permit him to lean outwardly beyond the edge of the cab, so as tobe able to see forward and back on the line of the track.

Having thus described my invention and its use, I claim- In a foldingcab-window, the combination with the sectional sash having spring-hingesdesigned to normally hold same closed, the lugs carried at thelower endsof the sashsections, of the hinged sill, the a-pertured spring-plates inwhich the said lugs are adapted to engage to hold the sash open, of thetop N hinged to the cab and having a rim about its free edge designed tofit over the upper ends of the sash-sections when opened, to cooperatewith the said lngs and spring-plates, to lock the window open, allsubstantially as shown and described.

In testimony whereof I affix my signature, in presence of two witnesses,this 7th day of May, A. D. 1895.
